π Food Web: Definition
A food web is a complex network of interconnected food chains within an ecological community. It illustrates the feeding relationships between various organisms, showing who eats whom in a more realistic and intricate manner than a simple food chain.
π± Ecological Pyramid: Definition
An ecological pyramid is a graphical representation of the trophic levels in an ecosystem. It depicts the flow of energy or biomass from one level to the next, typically showing a decrease in energy or biomass as you move up the pyramid.

β¨ Key Takeaways
- π Food webs show who eats whom in a complex ecosystem.
- β‘ Ecological pyramids represent the flow of energy or biomass between trophic levels.
- π± Food webs are more detailed but can be hard to visualize for large ecosystems.
- π Ecological pyramids are simpler but can oversimplify feeding relationships.
- π‘ Both are important tools for understanding how ecosystems function!
